The Lowdown
Right, let’s have a look at what the next couple of weeks are serving up at Jaconé. It’s a bit of a slow burner to kick things off, but there are a couple of proper windows in there that’ll get the blood pumping. We’re looking at a solid run of south swell starting this coming Sunday, and that’s where the real interest lies.
The first couple of days are pretty average. Friday morning has a touch of rideable 1ft, but the energy is weak (106), and it’s just not worth getting excited about. By Friday afternoon, it bumps up to 4ft with the wind going glassy, and it cleans up nicely. Saturday’s a write-off for anything decent, with the swell dropping right back and the wind swinging onshore.
Now, Sunday the 9th is where things start to get interesting. The swell jumps to 7ft from the SSW with a strong 14-second period, and the energy readings are through the roof at 1531. That’s a proper pulse of groundswell. The morning is looking clean with light cross-off winds, and it’s going to be firing. This is a standout window, and for the experienced crew among you, this is the one to point the car at. The waves will be solid, powerful, and clean.
After that, the energy stays high for a few days. Monday and Tuesday have 7ft to 8ft of south swell, with the energy staying well into three figures, peaking at 1787 on Tuesday morning. The wind is the main issue, though, with cross-onshore and cross conditions making it a bit lumpy. Tuesday afternoon, however, is a gem. The wind drops light cross-off, the waves are a solid 7ft, and the energy reads 1471. It’s going to be a much cleaner option than the morning before, and a real highlight for the week.
Wednesday the 12th keeps that good energy rolling, with clean 7ft waves in the morning under light cross-off winds. Thursday the 13th looks good too, with the swell easing slightly to 6ft, but the wind going glassy first thing. That’s a magic hour right there.
The following week, the strong SSW pulses keep coming. Friday the 14th has excellent 7ft surf with a long 14-second period in the morning and light offshore winds. The energy is massive again at 1819. Then things start to back off a touch. The weekend sees the swell drop to 6ft, and while the winds are mostly cross-off, the energy starts to wane. It’s still good, but not at the level of the mid-week stuff.
The real standout of this entire stretch, though, is the late swell. Tuesday the 18th flips direction to the east, with 5ft and an 8-second period under glassy conditions. The energy is down at 555, but it’s a fun, clean wave. Finally, Friday the 21st and Saturday the 22nd bring back some SSW swell, with 5ft to 5ft and clean conditions. Not as big, but still very rideable and clean for the end of the run.
So, to wrap it up: the best of the best is Sunday morning and Tuesday afternoon, with Thursday and Friday the following week also being prime. The rest is manageable, but those are the days to clear the calendar for. The water is sitting around average for the time of year.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
